I agree, there is not a goalie in the league that if he gets hot is as good as Gibson. With that said, other than the world juniors he really hasn't been that great. Very good...but not a show stealer. A lot of your success certainly depends on him.
Just thought of this now, but if you are really hoping to get Quine out of the 'borough you should be hoping to have them include '93 Clark Seymour who is 6'3 201 pounds and could bring some needed toughness on D. Now that would be a trade worth doing.
